MOLD FOR TROUGHS.

SPECIFICATION forming part of Letters Patent No. 735,385, dated August 4, 1903.

Application filed April 29, 1903.

To all whom it may concern:

Be it known that I, HENRY A. HUTTINGER, a resident of Defiance, in the county of Defiauce and State of Ohi0,'have invented certain new and useful Improvements in Molds for Troughs; and I do hereby declare the following to be a full, clear,'and exact description of the invention, such as willenable othersskilled in the art to which it appertainsto make and use the same.

My invention relates to an improvement in molds, and more particularly to improved molds for cement watering-troughs, the object of the invention being to provide improvements of this character which will permit of the easy removal of the mold after casting without injuring thefcastin g in the slightest. a

The inventon consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in elevation, illustrating my improvements; Fig. 2 is a top plan view. Fig. 3 is a view in section on the line a a, of Fig. 2. Fig. 4 is a View in section on the line b b of Fig. 3. Fig. 5 is an end View, and Figs. 6 and 7 are views illustrating details of construction.

1 represents the outside mold or casing, and 2 3 the inner molds or patterns. The outside mold or casing 1 comprises long side sections consisting of boards connected at their ends by bars 4, and rods 5 are secured in openings in said boards'and bars by nuts 6. These rods 5 are bent into hook shape at their inner ends to receive chains 7 for securingthe sides against the inclined edges of end sections 8 and firmly clamp the latter in place, forming a box with open top and bottom, straight ends, and inclined sides, as clearly shown.

The inside sections 2 and 3 comprise approximately semicylindrical frames,although they may be of other shapes, according to the interior shape of the trough desired. These sections 2 and 3 each comprise two members formed by securing a series of boards against the curved edges of vertical boards 9, one board 9 being located at the end of the side boards and the other some distance from the Serial No. 154,859. (No model.)

as shown, to permit one section to lie in the other and form a smooth outer surface and permit the sections to be knocked down and removed one at a time.

The operation of m yim provements is as fol lows': The'mold-sections 2 and 3 are centered in frame or casing 1 and the cement or other material cast between them. After it becomes sufliciently set the wedges 10 in section 2 are removed, when the members of section 2 canbe moved inward toward each other and removed. The section 3 is then removed in like manner and the chains 7 disconnected from the hooks on rods 5 and the outer frame or casing l removed, and after the rough places in the trough are smoothed it is left to harden. Of course suitable openings can be provided for the attachment of inlet and exhaust pipes, and various changes might be made in the general form and arrangement of the parts described without departing from my invention. Hence I do not confine myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

1. In a mold, the combination with an outside frame, of an inside mold comprising two semicylindrical sections having beveled overlapping ends, wedges holding the sections extended but permitting their collapse when removed, and tongues on the wedges to hold them in position.

2. In a mold for troughs, the combination of an outside frame comprising ends having inclined side edges, side sections against the inclined edges of the ends, hooks on the sides, and chains clamping said sides against the ends by their locking engagement with the hooks, and inside molds or patterns to be disposed in the center of said outside frame, substantially as set forth.
